CORTECO 12010885 NBR BA 30x50x10 mm - Rotary Shaft Oil Seal

CORTECO 12010885 - Technical Characteristics

CORTECO 12010885 is a radial shaft seal designed to restrict leakage of compatible lubricants at the interface between a rotating shaft and a stationary housing.

The BA construction features a rubber-covered outer surface that provides static sealing between the seal and the housing bore.

The primary NBR sealing lip operates in contact with the rotating shaft, while a circumferential garter spring helps maintain sealing contact.

The standard BA profile is a single-lip construction without an additional auxiliary dust lip.

The seal is associated with catalogue references for drivetrain components, including differentials and drive axles.

Compatibility with a specific vehicle or machine must be confirmed using the relevant OE reference and technical documentation.

CORTECO 12010885 - Dimensions

The 30 mm inside diameter corresponds to the nominal shaft diameter.

The 50 mm outside diameter corresponds to the nominal housing bore diameter.

The 10 mm axial width defines the nominal width of the sealing ring.

These dimensions do not independently establish installation tolerances, permissible shaft runout or the required surface roughness of the mating components.

CORTECO BA Oil Seal Construction

Rubber-Covered Outer Surface

The BA profile incorporates an internal metal supporting element covered externally by elastomer.

The rubber-covered outer surface provides static sealing between the oil seal and the housing bore.

Within the limitations of the seal design, the elastomer covering can accommodate minor irregularities in the housing surface.

Primary Sealing Lip

The primary NBR sealing lip operates in dynamic contact with the rotating shaft.

Its function is to restrict leakage of oil or another compatible operating medium from the sealed assembly.

Sealing performance depends on shaft surface condition, lubrication and operating parameters.

Circumferential Garter Spring

The standard BA construction incorporates a garter spring supporting the primary sealing lip.

The spring helps maintain contact between the sealing lip and the shaft surface.

The exact spring material depends on the manufacturer's specific execution.

Internal Metal Supporting Element

An internal metal element stabilises the seal geometry and provides structural rigidity during installation.

It is enclosed within the rubber-covered outer construction.

No Auxiliary Dust Lip

The standard BA profile is a single-lip construction.

It does not incorporate the additional auxiliary dust lip characteristic of the BASL profile.

Where increased protection against external contamination is required, the equipment manufacturer's sealing specifications should be checked.

NBR - Material Properties

NBR is a synthetic elastomer widely used in radial shaft seals.

Depending on the specific rubber compound, it can provide suitable compatibility with many mineral oils and lubricating greases.

When selecting CORTECO 12010885, the following factors should be considered:

• Type of oil or operating medium.

• Operating temperature.

• Shaft surface speed.

• Pressure within the sealed assembly.

• Condition of the mating shaft surface.

• Lubrication conditions.

• Exposure to contamination.

The NBR designation alone does not establish the exact operating temperature range, maximum permissible pressure or shaft surface speed of this particular oil seal.

CORTECO 12010885 BA vs Other Oil Seal Profiles

The table describes typical construction characteristics of these profiles. It does not establish automatic interchangeability.

BA vs BASL

BA is a single-lip construction.

BASL incorporates an additional auxiliary dust lip that helps restrict the entry of external contaminants.

BA vs B1

BA features a rubber-covered outer surface.

B1 has an exposed metal outer surface.

This difference affects static sealing between the seal and the housing bore.

BA vs B2

B2 features an exposed metal outer surface and a reinforced metal case.

It should not automatically be used as a replacement for BA without verifying installation requirements.

Applications of CORTECO 12010885

CORTECO 12010885 is catalogued in association with shaft sealing applications in drivetrain systems, including differentials and drive axles.

Its primary function is to restrict leakage of compatible lubricants from the sealed mechanical assembly.

The BA construction provides dynamic sealing against the rotating shaft and static sealing within the housing bore.

OE references associated with this product include components from DEUTZ, FENDT, LAMBORGHINI, MERCEDES-BENZ, NEW HOLLAND and SAME.

Compatibility with a particular vehicle, machine or gearbox model must be verified using the equipment manufacturer's parts catalogue.

Selection and Interchangeability

Before purchasing CORTECO 12010885, verify:

1. The CORTECO catalogue reference 12010885.

2. Nominal shaft diameter: 30 mm.

3. Nominal housing bore diameter: 50 mm.

4. Axial width: 10 mm.

5. NBR sealing material.

6. BA profile with a rubber-covered outer surface.

7. Primary sealing lip and garter spring construction.

8. Requirements for auxiliary dust protection.

9. Compatibility with the operating medium.

10. Operating temperature, pressure, shaft speed and installation conditions.

11. OE reference compatibility when selecting the seal for a specific vehicle or machine.

Matching nominal dimensions of 30x50x10 mm do not guarantee complete interchangeability.

CORTECO 12010885 BA should not automatically be replaced with a BASL, B1, B2 or different elastomer version.

Installation and Operating Considerations

Before installation, thoroughly clean the shaft and housing bore.

The mating shaft surface should be free from corrosion, scratches, burrs and wear grooves.

Protect the sealing lip when passing the seal over sharp edges, keyways or splines.

Install the oil seal evenly using an appropriate installation tool.

Do not apply installation force directly to the sealing lip or garter spring.

In conventional oil-retaining arrangements, the spring-loaded sealing lip faces the retained medium unless the equipment documentation specifies otherwise.

Before operation, ensure that lubrication is compatible with the NBR material and operating medium.
